NOTE: This equipment has been tested and found to comply with
the limits for a Class B digital device, pursuant to Part 15 of the
FCC Rules. These limits are designed to provide reasonable
protection against harmful interference in a residential installation.
This equipment generates, uses and can radiate radio frequency
energy and, if not installed and used in accordance with the
instructions, may cause harmful interference to radio
communications. However, there is no guarantee that interference
will not occur in a particular installation. If this equipment does
cause harmful interference to radio or television reception, which
can be determined by turning the equipment off and on, the user is
encouraged to try to correct the interference by one or more of the
following measures:
-- Reorient or relocate the receiving antenna.
-- Increase the separation between the equipment and receiver.
-- Connect the equipment into an outlet on a circuit different from
that to which the receiver is connected.
-- Consult the dealer or an experienced radio/TV technician for
help.
FCC Radiation Exposure Statement The modular can be installed
or integrated in mobile or fix devices only. This modular cannot be
installed in any portable device, for example, USB dongle like
Page 3
transmitters is forbidden.
This modular complies with FCC RF radiation exposure limits set
forth for an uncontrolled environment. This transmitter must not be
co-located or operating in conjunction with any other antenna or
transmitter. This modular must be installed and operated with a
minimum distance of 20 cm between the radiator and user body.
If the FCC identification number is not visible when the module is
installed inside another device, then the outside of the device into
which the module is installed must also display a label referring to
the enclosed module. This exterior label can use wording such as
the following: Contains Transmitter Module FCC ID: XCO-LS6 and
IC: 7756A-LS6
when the module is installed inside another device, the user
manual of this device must contain below warning statements;
This device complies with Part 15 of the FCC Rules. Operation is
subject to the following two conditions:
(1) This device may not cause harmful interference.
(2) This device must accept any interference received, including
interference that may cause undesired operation.
Changes or modifications not expressly approved by the party
responsible for compliance could void the user's authority to
operate the equipment.

The devices must be installed and used in strict accordance with
the manufacturer's instructions as described in the user
documentation that comes with the product.
Information for the OEM Integrators
This device is intended for OEM integrators only. Please see the full
grant of equipment document for restrictions.
Label Information to the End User by the OEM or Integrators
If the FCC ID of this module is not visible when it is installed inside
another device, then the outside of the device into which the
module is installed must be label with Contains FCC ID: XCO-LS6

LS6-N22S
1. Introduction
Libre LS6-N22S is a complete network media module. It includes an 802.11n MAC and baseband, a
2.4 GHz 2x2 MIMI radio and FEM, a 580MHz MIPS® 24K™ CPU core, with supporting FLASH and
DRAM memory. The module also includes all the necessary I/O and control interfaces required to
build feature rich networked media products, yet cost effective with very little additional electronic
design.
The embedded high performance CPU can process many advanced applications, such as network
media streaming, rendering, routing, security and special advanced Libre technology features. The
LS6-N22S also includes a selection of interfaces to support a variety of applications, such as I2S audio
interface, a USB port and SD port for accessing external storage, SPI and UART for data and control.
Combined with the extensive LibreSync software, this small form factor and low cost design provide
excellent Wi-Fi and processing performance for the wireless connectivity required in today CE
products.
